To all lwhom it may concern: Y, v

Be it known that I, CHARLES FRANCIS JENKINS, a citizen of the United States, re-

siding at Washington, in the District of Co lumbia, have invented certain new and useful Improvements in Repair Devices .for Pneumatic Tires, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to devices for permanently repairing cuts or punctures in pneumatic tires or in the casings of pneumatic tires; Cuts and punctures have been repaired by binding a pliable sheet such as leather or rubber and canvas, for examples, over the point of'injury, usually by lacing passing around the wheel rim. Such expedients are unsatisfactory for various reasons. Such a sheet is quickly worn; the tire or casing crawls within it opening a cut which should be left closed; and most im- A portant of all, the sheet gradually slips bodily upon the tire or casing bringing most of the very great strain or ull at one -margin of the laced part of t e sheet tearing 1t at this point.

TheJ rmcipal object of this invention is to pro uce a convenient, effective, durable and inexpensive dev ice which when applied to the outside of a tire or casing will avoid the evils suggested.

In the accompanying drawings,

Figure 1 shows partly in central longitudinal section a portion of a rim and tire provided with my devices.

'sof' other, around the rim. Through the inter-1v mediate portion of the sheet passvnumerous stout rivet-like studs, preferably of 'soft steel, having on the outer face of the sheet very broad preferably conical'he'ads or plates E. Each stud is passed through .the tread portion, provided with a thin washer F, and upset to form a somewhat sharply pointed projecting end G the base of which is spread out upon thesurrounding portion of the washer, which like the head E,is forced into 'the face ofthe sheet, the washer preferably being made ush with the surface of the sheet.

In applying the repair for a cut or punctture as .at H, for example, the tire is more or.v lessgpcompletely deated, the cut is closed so 4fari as it can be readily, and the sheet, with or without cement upon its inner face, is laced in position'as in Fig. '1.v The tire `being; then inated to full working pressure,

of the studs, so that the repair usually lasts as long as the other portions of the tire.

It may be observed that the repair may I be quickly made by unskilled persons with- Ithat usuall several ofthese sheets, of different widt s, are carried, with suitable lacing strips, ready for use.

What I claim is: y In devices of the class described, -the .out the aid of any tools or appliances, and
